Networking Arduinos Part 1

As I'm mainly preparing for my oral exam, I am still not 100% sure what my thesis project will be. But I like the idea of networking many arduinos together. So I spent some time figuring it out. 

I still prefer OSC messaging. However, when I was working with up to 6 wireless arduinos, it was getting difficult to connect them all at once. I think it was getting hard on the router. This is made so the transmitting arduino is reading one analog pin, it wirelessly sends the data to the receiving arduino, and then the receiving arduino sends the data through the serial port to Max MSP. The next step is making it so multiple arduinos are sending their sensor data to the receiving arduino. Also, converting the code to send other types of sensor data, not just analog voltage.
